    • An auto hammer has a housing, a grip portion and a striking device. The striking device has a striking rod that can strike a fastening element using a liner reciprocating motion. The striking device also has an associated clamping mechanism for clamping the fastening element. The clamping mechanism includes a clamping member, a driving part and a sliding member, wherein the clamping member is pivotally arranged in the sliding member and is connected to the driving part, and the driving part can rotate relative to the sliding member so as to cause the clamping member to rotate pivotally in the sliding member. The clamping mechanism may thus firmly clamp the fastening element in a manner that is convenient for users.
    • 自动锤具有壳体,抓握部分和击打装置。 打击装置具有能够使用衬管往复运动来撞击紧固元件的敲击杆。 打击装置还具有用于夹紧紧固元件的相关联的夹紧机构。 夹紧机构包括夹紧构件,驱动部和滑动构件,其中夹紧构件枢转地布置在滑动构件中并连接到驱动部,并且驱动部可相对于滑动构件旋转,从而 夹紧构件在滑动构件中枢转地旋转。 因此,夹紧机构可以以对用户方便的方式牢固地夹紧紧固元件。

    • The present invention relates to copolymer compositions for alcohol-selective membranes and methods of selectively separating an alcohol such as ethanol from an aqueous solution using such membranes. The copolymer compositions may be block copolymers of polystyrene-polybutadiene-polystyrene (hereafter “SBS”) having cylindrical morphologies; graft diblock copolymers synthesized by ring-opening metathesis polymerization of two cycloalkene monomers, wherein at least one of the cycloalkene monomers is substituted with one or more polydialkylsiloxane groups; or triblock copolymers comprising a middle block comprising a polymerized cycloalkene monomer and two end groups. The synthesized graft and triblock copolymer compositions may have a spherical, lamellar, cylindrical, double diamond, or gyroid morphologies. The copolymer compositions may contain a structural block that imparts essential mechanical properties to the membrane (e.g., polystyrene) and may also contain an alcohol transporting block (e.g., polydimethylsiloxane or polybutadiene). The copolymer compositions may have a domain spacing and a flux, where the flux increases as the domain spacing increases. The copolymer compositions may also have an alcohol separation factor that increases as the domain spacing increases. The separation method may be carried out using pervaporation or vapor permeation techniques.
    • 本发明涉及醇选择性膜的共聚物组合物和使用这种膜从水溶液中选择性地分离醇如乙醇的方法。 共聚物组合物可以是具有圆柱形状的聚苯乙烯 - 聚丁二烯 - 聚苯乙烯(以下称为“SBS”)的嵌段共聚物; 通过两个环烯烃单体的开环易位聚合合成的接枝二嵌段共聚物,其中至少一种环烯烃单体被一个或多个聚二烷基硅氧烷基团取代; 或包含包含聚合的环烯烃单体和两个端基的中间嵌段的三嵌段共聚物。 合成的接枝和三嵌段共聚物组合物可以具有球形,层状,圆柱形,双金刚石或旋转形态。 共聚物组合物可以含有向膜(例如聚苯乙烯)赋予必要的机械性能并且也可以含有醇输送嵌段(例如聚二甲基硅氧烷或聚丁二烯)的结构嵌段。 共聚物组合物可以具有畴间隔和通量,其中通量随着畴间距的增加而增加。 共聚物组合物还可以具有随着畴间距增加而增加的醇分离因子。 分离方法可以使用全蒸发或蒸气渗透技术进行。
